FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 223,554, dated January13, 1880.

Application filed J une 16, 1879.

To all whom t may concern Be it known that I, ANDREW'J. TERRY, of thecity and county of San Francisco, and State of California, have inventedcertain new and useful Improvements in Flour-Bolts; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the drawings accompanying thisspecification and forming a part of the same.

My invention has reference to certain improvements in hour-bolts; and itconsists in combining with annular recesses in the reelheadspacking-holding annular disks fitting in aforesaid recesses and ringsattached to said heads and fitted against the disks, substantially ashereinafter more fully set forth.

Referring to the accompanying drawings, Figure l is a longitudinalsection of lny improved flour-bolt, and Fig. 2 is a detached view of oneof the reel-heads seen from the inside.

Let A A represent the ends of the hutchbox. B C are two short tubes,which are secured in the same line in the opposite ends of the box, sothat they project both inside and outside of the box. Around each tube,inside of the box, is a fiange, d, which fits in a groove, 0, in thereel-heads, as hereinafter described.

The reel-heads E E have each a circularopening in its center, which islarger in diameter than the tubes B C, and smaller than the projecting'flanges d d.

The reel-shaft F passes through the center ofl each of the tubes B C,and is supported in boxes on the outside cross-beam, G, of the hutch-boxframe, while the heads E lit against the fianges d inside of the box.

A shallow recess, o, is made around the hole in each head E E on oneside, and in this recess the edges of the fianges d will f1t when theheads are pressed against them. A capring, g, is then secured to theinside of the heads after the iiangeis in place, thus forming a groovein the edge of the circular opening in each end, in which the outeredges of the anges move.

In securing the ilanges cl upon the tubes, I place a narrow piece ofsheep-skin, t', under them, so that the long wool will project up overthe joint between the head and ange, both inside and outside of thereel-head, and thus prevent the iour from getting into the joint.

The object of the combination of the parts lettered l g with therecessed reel-heads is to provide a packing around the openings in thereel-heads, through which the conve-yer and discharging-tubes pass. Thisarrangement of parts permits the ready and expeditious removal andreplacement of the individual parts and of the additional packing t'.

Around th atportion of the reel-shaft F which passes through eacl? ofthe tubes B C I secure a wide spiral iiange, j, in the manner ofconstructing screw-conveyers.

The tube B forms the feed-conveyer for feeding the hour into the bolt.The outside end of this tube therefore is open on top, so that the hourcan be delivered into it. The opposite tube, C, forms thedischarge-conveyer for removing the-tailin gs from the bolt. Its innerend is made open on top, so as to receive the tailings, while its outerend has an opening, l, on its under side, through which they aredischarged.

I thus provide a very simple arrangement for automatically feeding flourinto flour-bolts and discharging the tailings therefrom, and at the sametime I keep all the joints tight without unnecessary friction.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a flour-bolt, the combination, with the reel, whose heads E areprovided ou the inside with annular recesses o o, of the packing-holdingannular disks d, fitting in the recesses o of the heads, and the ringsg, attached to said heads and fitted against the disks d d,substantially as shown and described, for the purpose specified.

In witness whereof I have hereunto set my hand and seal.

ANDREW J. TERRY.
